phosphate and carbonate, lithium complex, dilithium phthalocyanine, and so on. Li K-edge XANES spectra have four or five peaks in the range from 50 to 90 eV, depending on the strength of chemical bonds between lithium ions and donor atoms. Li(1s) XPS spectra also have two or three peaks...
The Li 1s peak was clearly observed in these XPS spectra. In order to investigate the excitation energy dependence, the area ratio of the Li 1s and Mn 3p peaks in the XPS spectra was plotted against the excitation energy. As a result, when the excitation energy was 110 eV, the area ...
在电池 0.2C 与 0.5C 原位阻抗谱测试结束后,我们随后对这两个电池进行了倍率测试和循环测试,我们发现由于空间电荷层的出现,首次的高倍率充放电会恶化后续的电池性能。 ▲Figure4.S 2p (a) and Li 1s (b) XPS spectra at two interfaces (NCM/Li6PS5Cl interface and Li6PS5Cl/Li interface) of NCM/Li6...

Li(1s) XPS spectra also have two or three peaks in the range from 48 to 58 eV. The electron densities on lithium ions were obtained by DV-Xα molecular orbital calculation (8, 9). The relationship between these spectra and electron states will be discussed. Chemical structures of some ...
